How the Doubles Optimizer Works
In HYROX Doubles, each of the 8 workout stations must be completed by the team, but partners can divide the work however they choose. The optimizer categorizes stations as endurance-dominant or strength-dominant and assigns each to whichever partner has the predicted advantage in that category.
Endurance stations (SkiErg, Burpee Broad Jump, Rowing, Wall Balls) favor the partner with the faster 5K pace. Strength stations (Sled Push, Sled Pull, Farmers Carry, Sandbag Lunges) favor the partner with the higher deadlift-to-bodyweight ratio. The combined finish time estimate accounts for shared running segments and transition time between partners.
The even-split baseline shows what happens if you ignore individual strengths and divide every station 50/50. Even a modest difference between partners produces meaningful time savings when station types are matched to the right athlete across 8 stations.
How to Use the Doubles Recommendation on Race Day
Treat the recommendation as a starting plan, not a contract. The optimizer assumes both partners are equally fresh, equally efficient at handoffs, and equally good at the technique side of every station. Real Doubles teams are not. Walk through the recommendation in your last simulation session before race day and adjust where it does not match how you actually move together.
Two patterns matter more than the optimizer can see. First, who recovers faster between bursts. If one partner needs an extra 10 to 15 seconds to settle their breathing after sled push, give them the next endurance station and let the other partner lead the transition jog out of RoxZone. Second, who handles wall balls cleanly when fatigued. Wall balls are the last station and the easiest place to lose 30 to 60 seconds on missed reps. The partner with the more reliable rep cadence under fatigue should take the larger share even if the optimizer says otherwise.
Use the time gap between the optimized split and the even-split baseline as a coaching cue. A small gap, under 90 seconds, means the partners are well matched and either approach will work. A large gap, three minutes or more, means there is real money on the table and you should rehearse the assigned splits in training rather than improvising on race day. Run the optimizer again any time one partner's 5K, deadlift, or bodyweight changes by more than a few percent, since those are the inputs that move the recommendation.
